Abstract: Trust management technologies are crucial for the further and wider acceptance of pervasive computing solutions. These solutions were first addressed some fifteen years ago, but the proposed approaches were actually tackling security and not trust. Later, more advanced methodologies emerged that were based on Bayesian statistics. These were followed by Dempster-Shafer theory of evidence and its derivatives. In addition, some game theory based methodologies were developed as well. But trust is a manifestation of justification and assessment processes, which can be rarely assumed to be e.g. only rational, therefore trust should be treated in accordance with this fact. This plenary lecture will therefore provide an extensive survey of existing methodologies, and results of recent research focused on appropriate mentally ergonomic methodologies. Finally, it will present one mentally ergonomic trust management methodology called Qualitative Assessment Dynamics that complements existing methodologies mentioned above.
